All the gentlemen who attempt to replicate, My persona, my style, and my fate, With your trousers pulled up to your chest, Imitating my mannerisms, doing your best. But, I must confess, it is rather flattering, To see such dedication, your efforts battering. Yet, alas, my dear fellows, you are but mere shadows, For I am the genuine Slim Shady, who gallantly shows. My lyrics, my wit, a touch of the whimsical, Whilst you, dear imitators, remain so quizzical. For you shan't grasp the essence of my identity, I, the genuine Slim Shady, in all my verity.

Look at these film stars, in a grand parade, Engaging in affairs, causing scandals to cascade. But I, the genuine Slim Shady, stand resolute, For my dignity remains, unwavering and absolute. They ponder, "Will he make it in this theatrical realm?" But I, the genuine Slim Shady, take the helm. For I shall navigate this tempestuous sea, With poise and grace, you shall all see.

Thus, my dear audience, let us end this farce, For I am the genuine Slim Shady, and that is the crux. Ladies and gentlemen, I ask you to be clear, That I, the true Slim Shady, am standing here. So won't the real Slim Shady please stand up? Please stand up, please stand up. For I am the genuine Slim Shady, and there’s no doubt, Now let us bring this song to an end, without a doubt.
